The difference in volume between the two boxes would be = 156in³

To calculate the difference in volume between the boxes is the find the individual volume of the boxes using the formula ;

Volume = length×width×height.

For box 1 = length = 12in, width = 7¾in, height= 2in

Vol = 12×7¾×2 = 186in³

For box 2; length = 3⅔in, width = 3½in, height= 2⅓in

Volume = 3⅔×3½×2⅓ = 30

The difference = 186-30 = 156in³

Expressions that have the square root sign are said to be radicals.

The simplified form of \(-6i\sqrt{-44}\) is \(12\sqrt{11}\)

The expression is given as:

\(-6i\sqrt{-44}\)

Start by splitting the expression

\(-6i\sqrt{-44} = -6 \times i \times \sqrt{-44}\)

Factorize -44

\(-6i\sqrt{-44} = -6 \times i \times \sqrt{-1} \times \sqrt{44}\)

In complex numbers;

\(i = \sqrt{-1\)

So, we have:

\(-6i\sqrt{-44} = -6 \times \sqrt{-1} \times \sqrt{-1} \times \sqrt{44}\)

Express \(\sqrt{-1} \times \sqrt{-1}\) as \(-1\)

\(-6i\sqrt{-44} = -6 \times -1 \times \sqrt{44}\)

\(-6i\sqrt{-44} = 6 \times \sqrt{44}\)

Express 44 as 4 x 11

\(-6i\sqrt{-44} = 6 \times \sqrt{4} \times \sqrt{11}\)

Express \(\sqrt 4\) as \(2\)

\(-6i\sqrt{-44} = 6 \times 2 \times \sqrt{11}\)

\(-6i\sqrt{-44} = 12 \times \sqrt{11}\)

\(-6i\sqrt{-44} = 12\sqrt{11}\)

Hence, the simplified expression is: \(12\sqrt{11}\)

The z-scores of the scores are -1.34, -0.73, 0.48, 0.48 and 1.10

The sample scores are given as:

2, 3, 5, 5, 6.

Calculate the mean and the standard deviation using a statistical calculator.

From the statistical calculator, we have:

\(\bar x = 4.2\) --- mean

\(\sigma_x = 1.64\) --- standard deviation

The z-score is then calculated using

\(z= \frac{x - \bar x}{\sigma}\)

Where:

x = 2, 3, 5, 5, 6.

So, we have:

\(z_1= \frac{2 - 4.2}{1.64} = -1.34\)

\(z_2= \frac{3 - 4.2}{1.64} = -0.73\)

\(z_3= \frac{5 - 4.2}{1.64} = 0.48\)

\(z_4= \frac{5 - 4.2}{1.64} = 0.48\)

\(z_5= \frac{6 - 4.2}{1.64} = 1.10\)

Hence, the z-scores of the scores are -1.34, -0.73, 0.48, 0.48 and 1.10

The value of 0.045 × 2.05 / 0.0025 in standard form is 3.69 × 10.

To perform the calculation and express the answer in standard form, follow these steps:

Multiply 0.045 by 2.05:

0.045 × 2.05 = 0.09225

Divide the result by 0.0025:

0.09225 / 0.0025

= 36.9

Convert the answer to standard form by writing it as a decimal multiplied by a power of 10:

36.9 = 3.69 × 10

Therefore, the value of 0.045 × 2.05 / 0.0025 in standard form is 3.69 × 10.

Answer:

Step-by-step explanation:

If 11 flights were sampled with an 85% on-time arrival rate, the number of flights from the sample that arrived on time would be estimated to be 9.35, which would round to 9 flights.

This can be solved by:

(0.85x11)= 9.35

Since there can't be .35 of a flight, we would round to the nearest whole number, which would just be 9.

The final answer= 9 flights

fg(x) = 2x² +10x -28

Since this is an operation with functions. Let's multiply both functions and then check.

f(x) = x+7

g(x) =2x -4

f * g (x) = (x+7)(2x-4) Distribute the factors

fg(x) = 2x² -4x +14x -28

fg(x) = 2x² +10x -28

2) So the product of both functions, i.e. fg(x) = 2x² +10x -28

Answer:

  B. The graph of K has a greater y-intercept

  D. The graph of J has a greater slope.

Step-by-step explanation:

Given a table for function J and an equation for function K, you want to know which has the greater slope, and which has the greater y-intercept.

The y-intercept is the value of the function when x=0. We see from the table that y=2 corresponds to x=0 for function J.

We see from the equation for function K that the constant is 8. This is the value of y when x=0.

Function K has the greater y-intercept (8 vs. 2).

The slope is the change in y-value when x increases by 1 unit. We see from the table that y=7 when x=1, so the change in y from x=0 to x=1 is 7-2 = 5. The slope of function J is 5.

The equation for function K has an x-coefficient of 3. This means a change in x of 1 unit will result in a change in y of 3 units. The slope of function K is 3.

Function J has the greater slope (5 vs. 3).

Additional comment

Both functions are graphed in the attachment. The y-intercepts have their points labeled. The graph with the steeper slope is the blue line, function J.

The examples of error and trial method and quadratic system are shows below.

Number problems and try to solve either trial and error or a Quadratic System

Trial and error is a fundamental method of Problem solving. It is characterized by repeated, varied attempts which are continued until success, or until the agent stops trying. Until getting the right answer the problem is repeating through various steps. This type of problem solving is called trial and error method.

A linear quadratic system is a system containing one linear equation and one quadratic equation (which is generally one straight line and one parabola). A simple linear system contains two linear equations (which is two straight lines).

ERROR AND TRIAL METHOD

Question: 44 people live in eight houses (3 on each side of the Albert Square). Each house has a different number of people living in it. Each line of three houses has 15 people living in it. How many people live in each house?

Solution: Simplifying, we have to get 4 sets of numbers, each of which add up to 15. So start guessing.

The average number of people in a house is 44/8 is roughly 4.5. So what numbers should we take? 2, 3, 4, 5, 6, 7, 8, 9. Now, we should also have an average close to 5 for each set. Let's start:

Set 1: 3, 5, 7

Set 3: 2, 4, 9

Now, the other two sets will have an overlap. So let's guess the overlaps:

Set 2: Overlaps are 2 and 7. So the third number will be 6. Because we have not used 6 yet.

Set 4: Overlaps are 3 and 9. Then the third number ends up to 3 again. Wrong guess! So we need to try again. Overlaps are 3 and 4. In this case third number works out to be 8, which we have not used. So here is the answer

The first row: 2,6,7.

Second row: 4,8,3.

First column : 2,9,4.

Second column: 7,5,3.

QUADRATIC SYSTEM:

Find the points of intersection between the line y=2x+1  and the parabola y=x2−2.

Substitute 2x+1  for y in y=x2−2.

2x+1=x2−2

Write the quadratic equation in standard form.

2x+1−2x−1=x2−2−2x−10=x2−2x−3

Use the quadratic formula to find the roots of the quadratic equation.

Here, a=1,  b=−2,  and c=−3.

x=−(−2) ± (−2)2 − 4(1)(−3)√2(1)=2 ± 4 + 12√2=2 ± 42=3,  −1

Substitute the x-values in the linear equation to find the corresponding y-values.

x=3⇒y=2(3)+1

 =7x=−1⇒y=2(−1)+1      =−1

Therefore, the points of intersection are (3,7)  and (−1,−1).

14+1.75= 15.75

15.75+1.75=17.5

17.5+1.75=19.25

19.25+1.75=21

21+1.75=22.75

22.75+1.75=24.5

Starting with the given equation: 2 sin x cos x = cos x

By dividing both sides by cos x, we may simplify: 2 sin x = 1

Dividing both sides by 2:

sin x = 1/2

The values of x that fulfil sin x = 1/2 must now be found, and they are:

x = π/6 + 2πn or x = 5π/6 + 2πn, where n is any integer.

Therefore, the general solution is:
